SPOOL-SUPPORT FOR SEWING-MACHINES.

Patented Feb. 4, 1919.

Application filed April 12, 1918. Serial No. 228,237.

To all whom it may concern:

Be it known that I, JAMES T. DowoALL, a

citizen of the United States of America, residing at Woodhaven, Queens county, State of New York, have invented certain new and useful Improvements in Spool-Supports for SewingMachines, of which the following is a full, clear, and exact description.

' This invention relates to improvements in supports or holding devices for spools, reels, or the like, of cotton or sewing-thread employed in connection with sewingfmachines. My invention is particularly designed for use in connection with sewing machines for manufacturing purposes, that is to say, in establishments for manufacturing clothing or other articles, in large quantities. The sewing thread required for the above purpose is usually supplied in large quantities, that is to say, it is wound upon large spools or reels which are supported by standards placed adjacent'the machines. The location andmanner of supporting these spools or reels is not altogether satisfactory, as they take up valuable room, besides being in the Way of the articles which are being sewed. One of the objects of my invention is to provide a spool or reel support designed to firmly grip and maintain the spool above the machine, well out of the way. My improved support may be carried. by a stand ard or secured to the wall adjacent the machine, should the machine be located adjacent a wall.

Other features of improvement will be pointed out in the following specification, and illustrated in the accompanying drawin wherein:

Figure 1 is a diagrammatic view illustrating my improvement as applied'to a sewing machine;

Fig. 2 is an enlarged detail view of the spool-support proper, partly. in section, illustrated as applied to a wall or other similar support;

Fig. 3 is a similar view, the thread guide being broken off, illustrating the support arranged for attachment to a standard;

Fig. 1 is an enlarged sectional detail view of a portion of the spool-support; and

Fig. 5 is an enlarged cross sectional view thereof, the section being taken on a line 5-5 in Fig. 4.

My improvement consists mainly of a spool-holder suitably supported. adjacent a thread guide, the assembly being arranged for attachn'ient to a wall or the like, or to a standard. As herein embodied, the device comprises a spool-holder or arm comprising in this instance, two parts, one part consisting of a fixed solid member or rod 6 and a movable semicylindrical member 7, as is plainly indicated in Fig. 5. One end of the rod 6 is firmly held in a lug 8, carried by a plate 9, by a rivet '11, which also passes through the movable member"? of the' arm. The member 7 is loosely mounted upon the rivet and is capable of a radial or pivotal movement thereon.

The jaw 12 in the lug is beveled at one side, as at 13, to permit the arm-member 7 to be pivotally moved thereon. The object of moving the arm-member 7 is to provide an expansible and contractible arm or engaging device for a spool or reel, indicated by 14, carrying thread. The outer end of the fixed member 6 of the arm is provided with a sharp tooth 15, the other arm-member being also provided with a sharp tooth as at 16. The sharp teeth 15 and 16 serve to engage the core 17 of the spool to tightly secure same to the arm. In combination with the arm and plate 9, I provide a threadguide consisting of a supplemental arm 18 bent as at 19 and terminating in an eye 20 for the passage therethrough of the thread 21. Upon the supplemental arm or thread guide 18, I adjustably mount a follower or bracket 22 carrying a set-screw 23, the function of the follower or bracket being to serve as a backing for the spool or reel 14: to aid in positioning same in a sub stantially horizontal plane. When the spool or reel is placed upon the arm, the members thereof being contracted as in Fig. 5, it willbe moved up to the bracket 22. As the bracket is fiat, the spool will be caused to assume a horizontal position, after which the arm-members will be spread to engage the core of the spool. To spread the armmembers to cause them to grip the spool, I provide a threaded spindle or expanding de-' vice 24 which passes through a threaded opening -25 in the solid arm-member 6. The object of providing an arm consisting of a solid member and a semi-cylindrical member is to supply a structure which, when folded structure that can be reduced to small diameter so as to also accommodate small spools.

The plate 9 may be secured to a wall or the like, indicated by 26 (Fig. 2) by screws 27 or may be provided with a clamp 28' to engage a stand 29, as indicated in Figs. 1 and 3. In either case, my spool-support will be located so that the thread can beled -,to

bracket 22 is provided with an elongated slot 33 through which the spool or reel arm passes.

'VVhat I claim as my invention is:

1. A spool or reel support Comprising an arm, consisting of a cylindrical fixed member and a semi-cylindrical member pivotally mounted at one end adjacent the fixed end of thefixed member, a threaded spindle carried by the fixed member to force the movable member away from the said fixed member, a support for saidarm-members,

a thread guide adjacent the arm, a support for the arm and thread guide, and a bracket slidably mounted on the thread guide to serve as a backing for a spool on the arm.

2. A spool or reelvv support comprising an arm, consisting of a cylindrical fixed member and semi-cylindrical member pivotally mounted at one end adjacent the fixed end of the fixed member, a threaded spindle carried by the fixed member to force the movable nrember away from the said fixed member, a

5 support for-said arm-members, v a thread guideadjacent the arm, a, support for the arm and thread guide, a bracket slidably mounted on the thread guideto serve as a backing for a spool on the arm, and a tooth carried by each arm-member atthe free end thereof to engage the core of a spool.

3. A spool or reel support consisting of a support, alug carried ,therebyhaving a slot,

a fixed arm-member located at one side of said slot, a rivet passing through the lug and through said fixed arm-member, amovable arm-member loosely engaging said rivet at one end thereof, a threaded spindle carried by the fixed arm-member to operate the movable arm-member, a tooth carried by each arm-member at the free end thereofto engage the core of a spool, a bracktprovided .with a slot, said arm-members passing through said slot, and means to slidably support the said bracket. I

4. A spool 0rreel support consistingof a support, a lug carried thereby-having a slot, avfixed arm-member located'at one sideof said slot, a rivet passing through the-lug and through said fixed arm-member, a movable arm-member loosely engaging said rivet at-one end thereof, athreadedspindle carried by the fixed arm-member to operate the: movable-armmember, a tooth carried by each arm-member at the free end thereof to engage the core of a spool, a thread guide adjacent said arm-members, and..:- a bracket adjustably mounted on'sa-id thread guide and having-- a slot for thepassage therethrough ofsaid arm-members, said bracket acting as a backing fora spool. on said arm.

5. A spool or reel support consisting of a support, a lug carriedthereby having a slot,

a fixed arnrmember located at one sidelof' said slot, a rivet passing through the lug and through said fixed arm-member, a movable arm-member loosely engaging said rivet at one end thereof, a threaded spindle carried by thefixed arm-member to operate the movable arm-member; a tooth carried"-.by

each arm-member at the free end thereof for the passage of thread.
